HelloPharmacist Scorecard of Potassium Iodide 65 mg by Vitamatic

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Vitamatic Potassium Iodide contains one active ingredient: potassium iodide at 65 mg per tablet. The remaining ingredients are inactive — microcrystalline cellulose, dicalcium phosphate, stearic acid, colloidal silicon dioxide, magnesium stearate, and croscarmellose sodium — these are binders and fillers that hold the tablet together.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Potassium product and its label doesn't state a use — see Potassium's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

Our data does not hold effectiveness ratings for potassium iodide in this product. If you're considering it for a specific health purpose, talk with your doctor or pharmacist about whether the evidence supports its use for your situation.

The evidence, ingredient by ingredient Potassium

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Potassium from food is fine, but supplements can cause dangerously high blood levels in some people, especially those with kidney disease. Common side effects when taken by mouth include abdominal pain, belching, diarrhea, flatulence, nausea, and vomiting.

Rare but serious effects of high potassium are irregular heartbeat, heart block, low blood pressure, mental confusion, and bleeding from duodenal ulcers. During pregnancy, dietary potassium is appropriate, but use supplements only under medical guidance.

While breastfeeding, check with your doctor before using potassium supplements — there isn't enough data to know if they're fully safe. Our safety data advises against high-dose supplementation in pregnancy and lactation without professional oversight.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Potassium.
  • The most serious interaction on file is rated Moderate.
  • For scale: 62 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your doctor or pharmacist if you take potassium-sparing diuretics (Moderate risk), ACE inhibitors (Moderate risk), or angiotensin receptor blockers (Moderate risk). All three drug classes can raise blood potassium dangerously when combined with supplements.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This potassium supplement is for people who need extra potassium and don't take blood pressure or diuretic medications that affect potassium handling. If you take an ACE inhibitor, ARB, or potassium-sparing diuretic, you must clear this with your own doctor or pharmacist first — combining it could raise your potassium to unsafe levels.

Always discuss your full medication list before starting.

Potassium Iodide3 drug types · 62 drugs

Ace Inhibitors (Aceis)

Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Angiotensin Receptor Blockers (Arbs)

Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Potassium-Sparing Diuretics

Concomitant use increases the risk of hyperkalemia.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.

Potassium Iodide 65 mg by Vitamatic: Common Questions

Does Potassium Iodide 65 mg by Vitamatic interact with any medications?
Yes. Based on its ingredients, Potassium Iodide 65 mg has a known interaction with 62 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Potassium Iodide 65 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I have kidney disease?
Our data notes that supplements can cause dangerously high blood potassium in some people, especially those with kidney disease. Talk with your doctor or pharmacist — they know your kidney function and can tell you whether this is safe for you.
What are the most common side effects?
When taken by mouth, the most common side effects are abdominal pain, belching, diarrhea, flatulence, nausea, and vomiting. Most people tolerate it well, but these gastrointestinal effects do happen.
Is potassium from food different from this supplement?
Yes. Potassium from a normal diet is safe and fine. Supplements deliver much higher doses at once, so they carry more risk — especially of high blood potassium. That's why supplements should only be used under medical guidance.
Is it safe to take while pregnant or breastfeeding?
Dietary potassium during pregnancy is appropriate, but supplements should only be used under medical guidance. While breastfeeding, check with your doctor first — there isn't enough data to know if supplements are fully safe. Your doctor can give you personalized advice based on your situation.
Can this cause heart problems?
Yes, but it's rare. Very high potassium levels can cause irregular heartbeat, heart block, low blood pressure, or even cardiac arrest. This is why it's important not to combine it with medications that raise potassium, and why kidney disease is a concern.
